“…Thus such exposure to heavy metals (copper, lead and zinc) would have least effect on the seed and hence on its subsequent viability. Maisto et al (2004) used an accumulation factor, which they based upon the ratio between metal accumulated in Quercus ilex L. leaves and the concentration of metal in the soil surrounding the plant, as a method of comparing the accumulation of different metals. We have investigated the ratio between metal concentrations in soil and various plant tissues, but expressed this ratio as a percentage i.e.…”

Aspects of the bioaccumulation of heavy metals are reviewed and possible evidence of homeostasis is highlighted. Examination and analysis of olive (Olea europaea L.) trees growing in close proximity to a copper dominated spoil tip dating from at least 2000 years BP, on the island of Cyprus, revealed both bioaccumulation and partitioning of copper, lead and zinc in various parts of the tree. A factor to quantify the degree of accumulation is illustrated and a possible seed protective mechanism suggested. KEY WORDS Bioaccumulation, heavy metals, homeostasis, partitioning.The town of Polis is located in northwest Cyprus; the ancient Limni copper workings are approximately 8 km to the east of the town. The control site was situated on the Akamas peninsular approximately 25 km west of Limni. The prevailing winds are from the south west and should not affect the deposition of spoil tip derived particulates on the control site. The spoil tips adjacent to the sample collection site at Limni are large covering an area of approximately 2 x 2 km and are often steep sided and prone to atmospheric, sheet and gulley erosion (Pyatt and Birch, 1994) together with leaching during and following rainfall. Recently there has been a move to decrease the slope of the tip to reduce run off. The aims of the current research were to examine the commercially important plant species O. europaea (olives), currently growing in the close vicinity of the spoil tips, to determine copper, zinc, lead and cadmium concentration and the degree of partitioning. METHODS AND MATERIALS.Soil and spoil samples were collected using a clean stainless steel trowel. Approximately 5mm of surface soil and detritus in 20cm x 20cm area was scraped off and discarded. Approximately 200g of soil or spoil was then collected to a maximum depth of 50mm and placed in polythene bags. Each sample was individually triple bagged to prevent transit damage and transported to the laboratory. The spoil and soil samples were air dried for seven days in a drying cabinet at 25 0 C and placed in an oven for 3 h at 60 0 C. After cooling the samples were passed through a 2mm sieve and ground for 5 min in a clean pestle and mortar before transfer to HDPE storage bottles. 2Approximately 15g of olives were collected using clean stainless steel secateurs and the samples placed in a polythene bag; the samples were then triple bagged and transported to the laboratory. The olives were washed thoroughly with demineralised distilled water and dried for 24 h at 25 0 C in a positive pressure drying cabinet. They were then dried for 24 h at 70 0 C (Radofevic and Bashkin, 1999); after drying the flesh was separated from the stones using a clean stainless steel scalpel. Fleshy parts of olives were placed in a Waring Commercial Blender and blended at low speed for 2 min followed by 3 min at high speed, together with any oil which had exuded onto the storage dishes. Five seeds (stones) out of olives collected from Limni and the control site were placed in a clean 50 mL polypropylene centrif...

“…Roots holds Cu against the transport to aerial parts under conditions of Cu excess (Kabata-Pendias and Pendias, 2003) (TF > 1), and Cu concentrations in aerial parts are far above the critical values. Cu is assumed to generate mainly from the air in the aerial parts of linden and pine (Maistro et al, 2004).…”

The influences of airborne pollution originating from the Mining-Metallurgical Complex Bor (Serbia) on the concentrations of Cu, Pb, Zn and Mn in the samples of Tilia spp. and Pinus spp. were examined. The roots, branches, leaves/needles and soil were sampled in urban-industrial, rural and background zone at different distances from the copper smelter and at prevailing wind directions. According to the results of the enrichment factors, branches were the plant parts most enriched with Cu and Pb. The results of cluster analysis indicate that the most endangered zone in Bor is urban-industrial (at sites 0.5 km and 1 km away from the copper smelter). Aerial parts of both plant species can be used for biomonitoring of air pollution, although pine needles showed a higher level of response to pollution. According to the bioconcentration factor, translocation factor and translocation index, high concentrations of Cu and Pb in aerial parts of pine and linden are mostly a consequence of airborne pollution.

“…The use of leaves as bioindicators of environmental pollution has been studied, more and more, to assess their suitability (Maisto et al 2004;Tomasevic et al 2005;Rossini Oliva and Mingorance 2006), to assess effect of a specific pollution source (Madejon et al 2006;Aghabarati et al 2008), to differentiate between background (unpolluted) and polluted sites (Maisto et al 2004;Rossini Oliva and Mingorance 2006), and to monitor or assess the level of pollution in an area (Çelik et al 2005;Rossini Oliva and Mingorance 2006;Al-Khlaifat and Al-Khashman 2007;Gratani et al 2008).…”

Introduction In this study, olive tree leaves, collected from 50 sampling sites throughout the Province of Aydın, Turkey, were used to estimate level of pollution by measuring Al, As, B, Ba, Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb, Sr, and Zn concentrations and calculating pollution factor (PF) values. Materials and methods After sample preparation, collected leaves were microwave digested, and extracts were analyzed by an inductively coupled plasma-mass spectrometer. Results and discussion The maximum PF values were ≥10 for a number of elements ranging from 11-13 (Al, As, Cr, Fe, Mn, Ni) to >100 for Cu, Li, and Na. Urban-rural and roadside-nonroadside concentration comparisons showed that some of the elements (As, Cu, and Pb) were at significantly higher levels on urban and/or roadside sampling sites. Summary and conclusionCorrelations and factor analysis showed that there may be common sources for some elements, which included several soil types and anthropogenic activities. Based on the results of the statistical source apportionment, possible sources were narrowed down with help of the constructed elemental concentration maps. In conclusion, utilization of olive tree leaves for biomonitoring and assessment of environmental pollution was shown to be possible in the Mediterranean region where they are indigenous and cultivated.
